I'm interested in using the LDI LAS/TAC 2 Class 1 IR on a rifle. I've found threads saying that the power is good at over 250 yards without excessive bloom up close, which is an issue I have with my ITAL.
I can't find anything stating how the switch is activated. Is it momentary only, or momentary in one direction and constant-on in the other? What is the height off of the rail? Will I be able to see iron sights with the LAS/TAC 2 mounted on the top rail? |

Will I be able to see iron sights with the LAS/TAC 2 mounted on the top rail?[Yes/quote] The biggest issue I had with mine running it upside down on the top rail was changing batteries without removing the LAS/TAC2. I ended up dremel grinding a notch out of the rail so I could unlatch/latch the battery cover. I also used a piece of metal foil tape under the LAS/TAC2 so it sat solid on my rail with no movement. I have a Aimpoint micro and I can see the top of the LAS/TAC2 when I look through it but it does not obscure the sight picture much at all. The Magpul flip up front sight sits right behind the LAS/TAC2 which sits at the very front. Edit to add a pic:  |

I bought one for use with a rifle. Flip the switch one way and it is constant on. Flip the other way for momentarily on. When it is flipped momentarily on, you can see the beam move (since the housing is plastic and you are putting finger pressure on it). For me, to keep a constant zero, I must turn it to the constant on position and take my finger off the switch. The beam goes for hundreds of yards as seen through my PVS14...the beam goes for further than I can see to shoot via the PVS14 (I could see it hit a neighbor's mailbox that is probably a quarter mile away). It has PLENTY of power. I've not tried it on a pistol yet.
Height above rail - a hair under 1 1/4". Looking through my Eotech EXPS3-0, I can just see the top edge of the laser through the Eotech (laser mounted on top rail). Looking through my Aimpoint PRO, I can see a bit more of the laser, but nothing that would really interfere with using the Aimpoint. With iron sights and the laser at 12 oclock BEHIND the front sight, that won't work...the laser beam is centered on the rail and would hit the front sight base in my opinion. Note: I don't have a railed handguard with iron sights, but it appears it would not work...you would have to put the laser on the side rails or bottom rail or in front of the front sight. Edited to add: I think I'll try the metal foil tape under the laser to see if I can get it to hold better and try the momentary switch again. Thanks for the tip. |

How well do you hold zero, with the tape? Seems like it would be almost useless, if it shifts that easily. Unfortunate, since I really like the small size of the laser. It is more like a thick metal foil that is sticky on one side than regular tape. When in place it acts like a shim. With the tape, mine doesn't shift enough to notice. Without the tape it did slip forward and backward a bit. It is a pistol laser so is not really meant for long distance work like other rail mounted ir lasers. It clicks into place on the rail like a pistol weapon light would. In my photo above, it is mounted on a SBR'd and suppressed 9mm AR which it works fine for. IMO, ir lasers are not very good for precision anyway as they bloom way too much for precise shots. If you want sniper precision, buy a NV scope. |
